[Exim] Relay Problem with "x@y"@z

Hello,


Our Exim mailserver acts as a smarthost for several domains and sub-domains.
In config file, the local_domains is commented, the relay_domains is set with
a list of domains and host_accept_relay is set with our internal ip's

And there is a Router defined for the smarthost configuration.

The problem is that Exim accepts and delivers the mail where the receiver is
something like that : "x@y"@z, where z is a domain that exists in the
relay_domains variable.

I would like to reject this kind of mail, how do I to setup this thing ?

Thanx,

Kind regards,
